Description

TECHNICAL FIELD

[0002] In railway engineering construction, track maintenance and along the line material transportation operation, it is often necessary to use track transportation device to realize the efficient transfer of materials such as sand, parts and tools. The traditional track transportation device relies on the combination structure of simple frame and track wheel, and lacks targeted material protection and stable support design. On the one hand, when the material is directly placed on the surface of the frame, it is easy to cause position deviation due to the bumping and vibration in the transportation process, and even slide off from both sides of the frame, which not only causes material loss, but also may affect the safety of track passing.

[0003] At the same time, the safety hidden trouble of the existing track transportation device in the slope operation scene is particularly prominent. Most devices lack automatic locking function. When the device is pushed to the slope position by the staff and stopped or the pushing force is accidentally released, the track wheel is easy to slide down along the track due to gravity, which not only increases the operation burden of the staff, but also may cause safety accidents such as device collision and material dumping. While a few devices with locking function often need multi-step cooperation or additional tools for unlocking operation, which is complicated and slow in response, and is difficult to meet the efficient transportation operation demand. In addition, the traditional device is easy to produce lateral deviation in the moving process due to the insufficient guidance of the track wheel, especially at the curve track or track interface, the deviation phenomenon is more obvious, which further reduces the transportation stability and operation efficiency. Therefore, there is an urgent need for a railway track transportation device to solve the above problems. SUMMARY

[0016] This invention provides a railway track transport device. Through a self-locking component, when the worker pushes the device to a designated position and needs to stop, or when the device is accidentally released during pushing, the self-locking component automatically activates. At this time, a second spring located on the inner wall of the bearing seat pushes a second fixed seat through its elastic force, causing the brake gear on the second fixed seat to tightly engage with the fixed gear on the outer wall of the wheel axle, effectively preventing the track wheel from slipping. This ensures the safety of the device when stationary without additional operation. When the self-locking component activates, the rubber wheel, which is parallel to the track body, immediately resets. The rubber wheel then rotates to a perpendicular position to the track body, thereby forming a contact limit with the side of the track body through the side wall of the rubber wheel. On the one hand, the vertical rubber wheel provides additional constraint from the lateral direction of the track body, preventing lateral displacement of the device due to slight external impacts or minor track tilt when the device is in self-locking static position (especially when in a ramp position), further reinforcing the static stability of the device. On the other hand, the elastic material of the rubber wheel itself can reduce hard wear on the track body during the contact process. At the same time, its vertical position and the engagement structure of the brake gear and the fixed gear form a "two-way lock", that is, the brake gear restricts the rolling displacement of the track wheel, and the rubber wheel restricts the lateral displacement of the device. Under the dual protection, the safety of the device in the locked state is greatly improved, avoiding the risk of slippage or displacement caused by the failure of a single locking structure.

[0017] This invention provides a railway track transport device. By placing the material to be transported on a support plate on top of a support seat, the bottom of the support plate is connected to a partition plate by first springs distributed at equal intervals. With the help of the insert rods passing through the first springs and the fixing frame at the bottom of the insert rods, the device can not only buffer the impact force when the material is placed, preventing the material from being damaged by vibration, but also limit the displacement of the support plate by the insert rods, ensuring the stability of the material placement. At the same time, the enclosure and the baffle that can be locked in the bracket form a protective structure, which can prevent the material from falling from both sides of the support seat during transportation, further improving transportation safety. The entire device moves by the track wheels at both ends of the wheel axles on both sides of the support seat rolling along the track body. Attached Figure Description

When it is necessary to release the lock for movement, the staff pulls the pull rod 9 wrapped with the anti-slip sleeve 5, which moves the blocking ring plate 10 and the connecting column 11. The first rack 12 on the connecting column 11 moves and engages with the first gear 13, causing the first rotating column 16 and the first helical gear 15 to rotate. The first helical gear 15 then engages with the second helical gear 20, driving the second rotating column 19 and the second gear 18 to rotate. The second gear 18 drives the second rack 17 to move, and the second rack 17 pulls the connecting rod 21 through the rotating frame 22. The connecting rod 21 takes the second rotating seat 35 as the fulcrum and moves the push-pull rod 30 through the sleeve 31, causing the brake gear 43 to separate from the fixed gear 41, achieving quick unlocking of the self-locking assembly. At the same time, during the quick unlocking process of the self-locking assembly through the unlocking assembly, the third rack 46 moves when the second fixed seat 42 moves, engaging with the third gear 24 on the U-shaped plate 23 on both sides of the bearing seat 1 (the through slot 44 provides a stable rotating space for the third gear 24). The third gear 24 then engages with the fourth gear 25 on the rotating shaft 26, which can drive the first rotating seat 28 to rotate to a parallel state with the track body 7. At this time, the rubber wheel 29 can assist the track wheel 2 in maintaining the moving direction, reducing the deviation of the device during transportation and improving the moving stability. When the self-locking assembly is activated, the rubber wheel 29 in the parallel state with the track body 7 will immediately reset, and the rubber wheel 29 will rotate to a perpendicular state with the track body 7. The side wall of the rubber wheel 29 then forms a resistance limit with the side of the track body 7, providing additional constraints from the lateral direction of the track body 7 to prevent the device from deviating laterally when it is stationary (especially on a slope), further enhancing the stability of the device when it is stationary. On the other hand, the elastic material of the rubber wheel 29 can reduce the hard wear on the track body 7 during the resistance process, and its perpendicular state forms a "double locking" structure with the engagement structure of the brake gear 43 and the fixed gear 41, i.e., the brake gear 43 restricts the rolling displacement of the track wheel 2, and the rubber wheel 29 restricts the lateral deviation of the device, greatly improving the safety of the device in the locked state under the double protection, avoiding the risk of sliding or deviation due to the failure of a single locking structure.

[0039] The above merely provides the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
